1. Reproductive toxicology of endocrine disruptors : effects of cadmium, phthalates and phytoestrogens on testicular steroidogenesis
Sammanfattning : A number of investigations during the last two decades describe adverse trends in male reproductive health, which have been proposed to be caused by environmental factors with endocrine disrupting properties. In contrast to many other toxicants, endocrine disruptors often do not show linear dose-response relationships typical of those found in traditional toxicological studies. LÄS MER
2. Exploring the steroidogenic activity of glutathione transferases across species
Sammanfattning : Glutathione transferases (GSTs) comprise a superfamily of enzymes prominently involved in detoxication. However, some GSTs have developed alternative functions. LÄS MER
3. Regulation of apoptosis and steroidogenesis in ovarian preovulatory granulosa cells
Sammanfattning : Only a minute fraction of ovarian follicles present in a foetal ovary will complete the path to ovulation. The majority of the follicles will instead undergo atresia, a hormonally controlled apoptotic process. Apoptosis occurs throughout follicle development, with an extensive reduction in the number of follicles present at birth. LÄS MER
4. Enzymatic Regulation of Steroidogenesis and Nuclear Receptor Activation : Special Focus on Vitamin D and Sex Hormones
Sammanfattning : Enzyme-catalyzed reactions are important to regulate steroidogenesis and nuclear receptor activation. The present investigation examines the role of steroid metabolism catalyzed by CYP7B1 for regulation of hormone receptor activation and the effects of vitamin D on enzymatic regulation of steroidogenesis.

5. Alpha-class Glutathione Transferases from Pig: a Comparative Study
Sammanfattning : Glutathione transferases (GSTs, EC 2.5.1.18) possess multiple functions and have potential applications in biotechnology. LÄS MER
